A li ati fil d September 18, 1895. Serial No. 562,858. (No model.)

To aZZ whom it ntay concern.-

Be it known that I, GEORGE A. ENSIGN, of Defiance, in the county of Defiance and State of Ohio, have invented a new and useful Improvement in Sewer-Inlets, of which the following is a full, clear, and exact description.

My invention relates to an improvement in catch-basins or inlets for sewers; and the obj ect of the invention is to so construct a catchbasin or sewer-inlet that it will be practically impossible to injure it by a sudden addition of weight, such as may be caused by a loaded wagon or a crowd of pedestrians passing over it.

A further object of the invention is to so construct the sewer-inlet or catch-basin that its cover cannot be removed by children thus lessening materially the danger attending that class of inlets provided with loose removable covers, and, furthermore, to so construct the cover that it may be attached to the body of the inlet or basin by means of a lock of any approved construction.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference inclicate corresponding parts in all the figures.

Figure 1 is a plan view of the catch-basin or inlet with its cover removed. Fig. 2 is a section taken substantially on the line 2 2 of Fig. 1, the cover being in position on the body of the basin. Fig. 3 is a front elevation of the grating employed in connection with the basin, and Fig. 4: is a section taken substan tially on the line a a of Fig. 1.

In carrying out the invention the body A of the casing is substantially angular in general contour, or somewhat V-shaped, being preferably rounded at the junction of its members instead of angular at that point, and the body or casing of the basin may be of any desired depth, being open at the top and provided with a substantially conical collar 10 in its bottom, surrounding an opening 11 therein, the lower or contracted end of the collar being likewise open, in order that it may be coupled in any approved manner with a sewer-pipe.

The front of the body or casing is open, and the bottom at the front edge is provided with a countersink or a depression 12 in its upper face, the said countersink or depression being adapted to receive the lower web of a grating B, adapted to constitute practically the front of the body, and the grating at each end has a vertical groove 13 made therein, adapted to receive inwardly-extending vertical flanges 14, made upon the inner face of the casing or body at its forward end, as is best shown in Fig. 1.

At the central portion of the rear of the casing or body, near the top, upon its inner face, a step 15 is formed, and above the step a flange 16 is made, preferably integral with the upper edge of the casing, while at each side of the casing, upon its inner face, a projection 17 is constructed, preferably integral with the said upper edge of the casing, as is also shown in Fig. 1.

In order to facilitate the attachment of the body or casing to a convenient support, a horizontal flange 18 is attached to or made integral with the rear portion of said casing and a portion of its sides, as is illustrated best in Fig. 1.

A cover 0 is adapted to close the top of the body or casing and is made of similar con tour thereto. This cover is provided with an angular rearwardlyextending tongue 19 upon its under face, at its central rear portion, be ing adapted to enter the space between the step 15 and the lug 16, as shown in Fig. 2, a

and at each side of the said cover, on its under face, an angular or substantially L-shaped lip 20 is constructed, the lips being adapted to be coincident with the projections 17 on the casing. It will therefore be observed that while the cover is readily removable it cannot be readily lifted off by children or inexperienced persons, and in order that said cover shall not be removed except when there is need a pin 21, preferably in the nature of a cotter-pin, is passed through the forward central portion of the cover and through an opening 22 made in the top web of the grating. This pin is preferably a split pin, and if in practice it is found desirable the lower end of the pin maybe apertured to receive a padlock or an equivalent device.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a sewer-inlet or catch-basin, the combination with the casing or body thereof, of a removable grating adapted to interlock with the front portion of the said body or casing, and a removable cover for said casing or body adapted for interlocking engagement therewith, the forward portion of the said cover being adapted when in position to rest upon the top of said grating, substantially as shown and described.

2. In a sewer-inlet or catch-basin, the combination,with the body or casing thereof, of a removable grating, a removable cover, and interlocking devices normally securing the cover to the body or casing, and a locking device between the cover and grating, as and for the purpose set forth.

3. In a sewer-inlet or catch-basin, the combination with a casing or body open at the front and provided with inwardly-extending vertical flanges upon its inner face at its forward end, of a removable grating for the front of the casing, the said grating having a vertical groove at each end adapted to receive the said flanges at the forward end of the casing, a sliding cover adapted for interlocking engagement with the casing or body, and a fastening device between the said cover and grating, substantially as specified.

4:. In a catch-basin or sewer-inlet, the combination, with a body or casing provided with an exterior flange adapted for attachment to a support, and a grating removably located at one side of the casing or body, of a cover having interlocking connection with the body, and a locking device adapted for attaching the cover to the grating, as and for the purpose specified.

5. In a sewer-inlet or catch-basin, the combination, with a body or casing open at the top and at one side, the open side having a depression in its bottom, a step formed upon the rear portion of the casing near its top, a lug likewise formed on the casing and located above the step, and projections forming a portion of the sides of the casing, of a grating seated in the depressed portion of the open end of the body or casing, a slidable cover provided with an angular tongue adapted to enter the space between the step and the lug of the casing, and likewise provided with angular lips adapted for engagement with the projections of the casing, and a locking device connecting the cover with the grating, as and for the purpose set forth.
